Distribution. Japan ( Takahashi, 1958); Taiwan ( Takahashi, 1932). The record from Hong Kong by Martin & Lau (2011) refers to T. crypta sp. nov.

Host plants. Machilus sp. ( Lauraceae ) ( Takahashi, 1932), Actinodaphne sp., Cinnamomum zeylanicum , Cinnamomum sp. ( Lauraceae ) ( Takahashi, 1933); Neolitsea [ Tetradenia sp.] sp. ( Lauraceae ) ( Takahashi, 1935); Eurya loquaiana (Pentaphylacaceae) , Litsea hypophaea , Machilus zuihoensis (Lauraceae) (new records).

Remarks. Takahashi (1935) recorded two hosts, Actinodaphne sp. and Cinnamomum sp. for T. actinodaphnis , and mentioned his fresh collections of T. machili were commonly found on these hosts, thus, he included both host plants for T. machili and also referred to Takahashi (1933). The examined syntypes and other puparia determined by Takahashi have a pair of tubercles cluster on pigmented submedian area of metathorax, whereas the puparia of T. actinodaphnis lack such tubercles cluster. However, freshly collected puparia did not show such pigmentation. Puparia examined from Litsea acuminata had dorsal tubercles twice longer than those from Machilus zuihoensis . Examination of a large number of puparia mounted by Takahashi, type specimens of T. actinodaphnis and our fresh collections revealed that the elevation of dorsal tubercles bearing seta varies in T. machili , but the “position of setae” and their number remained constant in all the specimens examined in this study, and this supports separation of T. machili from T. actinidaphnae along with other characteristics- the position of vasiform orifice anterior to puparial caudal margin. In adult males, the upper and lower lobes of compound eyes were joined by three facets ( Fig. 41 ) and two facets in females. Antenna seven segmented ( Figs 43, 44 ), 4 primary sensoria, two on segment III, subapically and one each on V and VII; 3 sensorial cones, one each on segment III, V and VII. Claspers with subapical tooth and inflatable sacs ( Fig. 45 ). Puparia of Aleurocanthus woglumi (Ashby) , Dialeuropora decempuncta (Quaintance and Baker) and Rhachisphora machili Takahashi were found feeding on same host plant leaves.
